Description

Technical Field

[0001] This utility model relates to the field of auxiliary installation technology for diagonal web members, and in particular to a positioning device for diagonal web members. Background Technology

[0002] The installation of diagonal web members is a crucial step in the construction of steel trusses. Diagonal web members typically connect the top and bottom chords of the steel truss, serving to transfer loads and enhance structural stability. However, in actual construction, due to factors such as the weight of the diagonal web members themselves and their installation location, it is often difficult to precisely align the web members with the top or bottom chords, preventing the web members from being hoisted and installed in one go. This not only increases the difficulty of construction but may also lead to delays and increased construction costs.

[0003] Traditional methods for installing diagonal braces typically rely on manual adjustment or the use of simple auxiliary tools for hole alignment, but these methods have the following problems:

[0004] 1. Manual adjustment makes it difficult to ensure precise alignment between the diagonal web members and the upper or lower chord beams, which can easily lead to deviations.

[0005] 2. Repeated adjustments and hoisting processes are time-consuming and labor-intensive, affecting the construction progress;

[0006] 3. In high-altitude operations, frequent adjustments and hoisting increase the safety risks for construction workers.

[0007] Therefore, there is an urgent need for a positioning device that can precisely adjust the position of the diagonal web members to ensure that the diagonal web members are accurately aligned with the upper or lower chord beams, thereby enabling the diagonal web members to be hoisted and installed in one go. Utility Model Content

[0008] In view of the shortcomings of the existing technology, this utility model provides a positioning device for a diagonal web member, so as to solve the technical problem that the diagonal web member and the upper or lower chord beam cannot be accurately aligned with the hole in one go in the related technology.

[0009] This utility model provides a positioning device for a diagonal web member, which is applied to a steel truss beam. The positioning device includes two independent positioning bases, and a receiving opening is configured between the two positioning bases to accommodate a lifting mechanism, so that one of the two positioning bases can move relative to the other to correct the diagonal web member.

[0010] The positioning base includes a mounting plate and a support plate. The mounting plate has multiple mounting holes, and the support plate is perpendicular to the mounting plate and is used to support the lifting mechanism.

[0011] Furthermore, the support plate divides the mounting plate into a first mounting part and a second mounting part. The connection between the first mounting part and the support plate is provided with a reinforcing structure. The second mounting part extends toward the receiving opening and is used to install the lifting mechanism.

[0012] Furthermore, the reinforcement structure includes a plurality of first reinforcing ribs, and a plurality of second reinforcing ribs are provided at the connection between the first reinforcing ribs and the support plate, wherein the first reinforcing ribs and the second reinforcing ribs extend in different directions.

[0013] Furthermore, the mounting hole is formed in the first mounting portion and / or the second mounting portion.

[0014] Furthermore, the plurality of mounting holes are spaced apart along the length and / or width directions of the first mounting portion and / or the second mounting portion.

[0015] Furthermore, the positioning base also includes two limiting plates, which are spaced apart at opposite ends of the support plate, and the first and second ends of each limiting plate are respectively fixed to the first mounting part and the second mounting part.

[0016] Furthermore, any two of the first mounting part, the second mounting part, the support plate, and the limiting plate are arranged perpendicular to each other.

[0017] Furthermore, one of the two positioning bases is defined as a movable positioning base and the other as a fixed positioning base. The support plate of the movable positioning base is provided with a first guide rod, and the support plate of the fixed positioning base is provided with a second guide rod. The first guide rod can move synchronously with the movable positioning base and can slide relative to the second guide rod.

[0018] Furthermore, the lifting mechanism is a jack.

[0019] Compared with existing technologies, this utility model has the following advantages: one of the two positioning bases is used to be installed at the upper or lower chord of the steel truss beam, and the other is used to be installed at the diagonal web member. After the diagonal web member is initially hoisted into place, the positioning base installed at the diagonal web member is driven to move by the jacking mechanism so that the two can quickly align with the hole and improve the installation accuracy and efficiency of the diagonal web member. Furthermore, the mounting plate of the positioning base has multiple mounting holes, which not only allows the positioning base to be installed at different components, improving the versatility of the device, but also improves the stability of the installation connection between components. At the same time, the support plate of the positioning base can cooperate with the receiving opening to support the jacking mechanism, eliminating the need for additional parts to fix the jacking mechanism, facilitating the assembly and disassembly of the jacking mechanism, thereby reducing the risk of high-altitude operations.

[0026] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0027] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the technical solutions of this utility model are further described below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of this utility model and are not intended to limit it.

[0028] In the embodiments of this utility model, such as Figures 1-3 As shown, the positioning device for the inclined web member includes: two independent positioning bases, with a receiving opening 4 between the two positioning bases configured to accommodate a lifting mechanism, allowing one of the two positioning bases to move relative to the other to correct the inclined web member; the positioning base includes: a mounting plate 1 and a support plate 3, the mounting plate 1 having multiple mounting holes 2, and the support plate 3 being perpendicular to the mounting plate 1 and used to support the lifting mechanism.

[0029] Specifically, in this embodiment of the utility model, the steel truss includes upper and lower chord beams and diagonal web members connecting the upper and lower chord beams. Since the diagonal web members are installed in the same way on the upper and lower chord beams, the installation of the diagonal web members and the upper chord beam is used as an example in this embodiment for explanation.

[0030] In this embodiment of the invention, two independent positioning bases are provided. One of the positioning bases is fixed to the upper chord beam, and the other is fixed to the diagonal web member. A lifting mechanism is provided between the two. Thus, the lifting mechanism can drive the positioning base connected to the diagonal web member to move, allowing the diagonal web member to be aligned with the holes in one go during hoisting. Specifically, the position of the diagonal web member is corrected so that the holes on it correspond to the holes on the upper chord beam, facilitating the fixing of the diagonal web member to the upper chord beam. Furthermore, the two independently provided positioning bases facilitate the movement of one positioning base relative to the other under the drive of the lifting mechanism, and allow each component to be stored independently when not in use, reducing the footprint of the device.

[0031] In this embodiment of the utility model, the positioning base includes a mounting plate 1 and a support plate 3 that are perpendicular to each other. The mounting plate 1 has a plurality of mounting holes 2 so that the positioning base can be fixedly installed at the corresponding upper chord beam or diagonal web using fasteners such as bolts. The support plate 3 can play the role of supporting the lifting mechanism; that is, the movable end and the fixed end of the lifting mechanism are respectively positioned at different support plates 3 of the two positioning bases.

[0032] This embodiment utilizes the cooperation of mounting plate 1 and multiple mounting holes 2 to fix the positioning base at different components, improving its versatility. Furthermore, the support plate 3 serves as a support point for the lifting mechanism, facilitating the movement of the corresponding positioning base and thus quickly correcting the position of the diagonal bracing. This process reduces or eliminates manual intervention, lowering the risks of working at heights and ensuring the diagonal bracing is corrected in one go, eliminating the need for repeated adjustments and improving installation efficiency. This positioning device offers numerous advantages, including precise adjustment, efficient construction, reduced difficulty, enhanced safety, strong adaptability, and lower costs, improving the quality and efficiency of steel truss diagonal bracing installation.

[0033] like Figures 1-3As shown, in one embodiment, the support plate 3 divides the mounting plate 1 into a first mounting portion 101 and a second mounting portion 102. A reinforcing structure 5 is provided at the connection between the first mounting portion 101 and the support plate 3. The second mounting portion 102 extends towards the receiving opening 4 for mounting the lifting mechanism. Specifically, to improve the structural strength of the positioning base and facilitate the installation of the lifting mechanism, this embodiment defines the mounting plate 1 on one side of the support plate 3 as the first mounting portion 101 and the mounting plate 1 on the other side as the second mounting portion 102. A reinforcing structure 5 is provided at the connection between the first mounting portion 101 and the support plate 3, thereby improving the structural strength at that location. Furthermore, the second mounting portion 102 extends towards the receiving opening 4 to facilitate its use as a mounting base for the lifting mechanism. During installation, since the installation distance between the two positioning bases should not be too wide, the two second mounting portions 102 of the two positioning bases can form a mounting platform, allowing the lifting mechanism to be placed on this platform without additional fixing structures, thus simplifying the structure and making the operation more convenient.

[0034] like Figures 1-3 As shown, further, in one embodiment, the reinforcing structure 5 includes a plurality of first reinforcing ribs 501, and a plurality of second reinforcing ribs 502 are provided at the connection between the first reinforcing ribs 501 and the support plate 3. The first reinforcing ribs 501 and the second reinforcing ribs 502 extend in different directions. Specifically, in order to improve the structural strength of the first mounting part 101 and the support plate 3, this embodiment provides a first reinforcing rib 501 at the connection between the first mounting part 101 and the support plate 3, and provides a second reinforcing rib 502 at the connection between the first reinforcing rib 501 and the support plate 3, with the two reinforcing ribs extending in different directions, thereby improving the structural strength at that location. Of course, the first reinforcing ribs 501 and the second reinforcing ribs 502 described above can both be multiple to prevent the first mounting part 101 and / or the support plate 3 from being bent.

[0035] like Figures 1-3 As shown, in one embodiment, the mounting holes 2 are formed in the first mounting portion 101 and / or the second mounting portion 102. Specifically, to improve the versatility of this device, this embodiment provides mounting holes 2 at both the first mounting portion 101 and the second mounting portion 102, allowing for the adaptation of mounting hole 2 positions to different components. This facilitates the random selection of the positioning base for installation on different components, improving the versatility and reusability of the device. Preferably, a plurality of mounting holes 2 are spaced apart along the length and / or width directions of the first mounting portion 101 and / or the second mounting portion 102.

[0036] like Figures 1-3As shown, in one embodiment, the positioning base further includes two limiting plates 6, which are spaced apart at opposite ends of the support plate 3. The first and last ends of each limiting plate 6 are respectively fixed to the first mounting portion 101 and the second mounting portion 102. Specifically, to further improve the structural strength of the positioning base and to confine the lifting mechanism within the aforementioned mounting platform, this embodiment fixes two limiting plates 6 at opposite ends of the support plate 3, allowing the support plate 3 and the two limiting plates 6 to form an "I"-shaped structure. The limiting plates 6 are fixed to the mounting plate 1, meaning that the first and last ends of the limiting plates 6 are welded to the first mounting portion 101 and the second mounting portion 102, with each plate integrally formed to constitute a whole, thereby improving the overall stability and structural strength of the positioning base. Furthermore, the limiting plate 6 located in the second mounting portion 102 can at least partially close the receiving opening 4, so that the limiting plate 6 and the second mounting portion 102 can be configured into an upward-facing open structure. This open structure can be configured as the receiving opening 4, so that the lifting mechanism only needs to be placed there, which is convenient for assembly and disassembly. Preferably, any two of the first mounting portion 101, the second mounting portion 102, the support plate 3, and the limiting plate 6 are arranged perpendicular to each other.

[0037] like Figures 1-4 As shown, one of the two positioning bases is defined as a movable positioning base and the other as a fixed positioning base. The support plate 3 of the movable positioning base is provided with a first guide rod 701, and the support plate 3 of the fixed positioning base is provided with a second guide rod 702. The first guide rod 701 can move synchronously with the movable positioning base and can slide relative to the second guide rod 702. Specifically, in order to constrain the movement path of the positioning base, this embodiment sets up a guide structure 7, which allows the positioning base to move smoothly under the guidance of the guide structure 7. The guide structure 7 includes a first guide rod 701 and a second guide rod 702, which are respectively installed at different positioning bases and can move relative to each other, so that the corresponding positioning base can move smoothly under the guidance of the corresponding guide rod.

[0038] Specifically, one of the two positioning bases is defined as a movable positioning base, with its support plate 3 being a movable support plate; the other is defined as a fixed positioning base, with its support plate 3 being a fixed support plate. The first guide rod 701 and the second guide rod 702 are respectively mounted on the movable support plate and the fixed support plate. Simultaneously, the aforementioned guide structure 7 also includes a guide frame 703, which has a movable through hole and a fixed through hole. The first guide rod 701 and the second guide rod 702 pass through the movable through hole and the fixed through hole respectively. The first guide rod 701 has a clearance fit with the movable through hole, while the second guide rod 702 has an interference fit with the fixed through hole. Therefore, the first guide rod 701 can move along with the movable positioning base, allowing it to slide within the movable through hole, thus achieving relative movement between the first guide rod 701 and the second guide rod 702. Of course, to prevent the first guide rod 701 from sliding out of the movable through hole, a stop 704 can be provided at its end for limiting its movement. Furthermore, for ease of storage, since the first guide rod 701 and the second guide rod 702 cannot be separated due to the restriction of the stop 704, a screw is provided at the stop 704, and a threaded hole is provided at the end of the first guide rod 701. The screw is screwed into the threaded hole to achieve a detachable connection between the stop 704 and the first guide rod 701. Releasing the stop 704 allows the first guide rod 701 to be removed from the movable through hole, thereby disassembling the two positioning bases for easy storage. In addition, the first guide rod 701 can be threadedly connected to the movable support plate. By rotating the first guide rod 701 forward and backward, its extension length can be changed, thus allowing for adaptive adjustments according to the position of the corresponding positioning base to ensure an effective connection between the first guide rod 701 and the second guide rod 702.

[0039] The lifting mechanism is a jack (not shown).

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
